Zipo, I'm so confused as to how your challenge is working. 21 challenges, seriously?
Anyway, you're character likes food. (Greedy).
Also, the only HP healing items you can use once you get past Rock Tunnel are Fresh Water, Soda Pop, Lemonade and Moomoo Milk. (Although Moomoo milk will only apply if you're going through the post-game as you can only get it from Two Island, once the E4 is beaten.)
